The drawing below shows Dantherm’s suggestion on how to connect the water cooled condenser to the swimming pools water supply. -
Page 19: Lphw Coil
3. INSTALLATION 3.3.10 LPHW coil The supply is always connect to the bottom of 1 and 2 row LPHW coils, as this makes it easy to bleed the coil for air. If the coil is larger than 2 rows, the water and air flow must be counter flow to obtain the calculated heat capacity. -

4. COMMISSIONING 4.1 Introduction When servicing on air handling units always turn off the electricity on the main switch and the repair switch (complete shut down) and secure for reconnection from unauthorized persons. Only open the inspection doors when the unit is totally stopped and the fans have come to a stop. -

Page 26: Pressure Transducer
4. COMMISSIONING If you want to lower the air volume to 4000 m /h you have to change parameter 215 (air volume min set point) in the frequency converter. The calculation for the value is done with the following formula: Value = Where Par205 is parameter 205 (Max pressure transducer setting, see 4.3.3) and k the nozzle coefficient. - Page 27 4. COMMISSIONING If the green LED is flashing you have to change the pressure range setting. Change of setting can be done with the DIP switch 1-3 (2). This can be the case if you run with a higher or lower air volume than first designed. The pressure range depending on the DIP switch setting can be seen below.
